It is also quite frustrating when a native speaker is completely unable to understand something you say because of a tonal issue. To their ear it must sound entirely different, yet to a non-tonal ear it sounds like you're saying everything 'almost' exactly correct.
Likewise, learning to speak the tone is just another grammar dimension, memorization.
Listening for tone is the hard part, but once you know enough grammar AND know the context of the sentence, it falls into place.
YMMV, also Cantonese is more difficult here (IMO).
Why would you want to? Pitch also provides connotations / emotions in Mandarin.

That will never happen. Your bad pronunciation can aggravate other problems, but if your sentence is otherwise good, ignoring the tones will still leave it fully intelligible.
(I once asked a student in a Chinese school whether a particular class wasn't occurring, and he responded "poss". After some confusion, he was frustrated that the pronunciation difference between "poss" and "pause" should make such a difference in communicating with an English speaker.
But of course, it doesn't. If "pause" were a valid way to respond to "is chemistry class happening today", I would have had no difficulty understanding "poss". His problem was in bad knowledge of the language, not bad pronunciation.
You appear to be making the same mistake here. If you try to communicate, and fail, that is not evidence that you are qualified to diagnose what the problem was.)
So i kind of suspect it might also be the case for chinese: tones and the alphabet are obscuring a clean grammar.
I agree that written Vietnamese is relatively straightforward. It isn't that difficult to read to the eyes of someone used to latin script.
Vietnamese is massively harder to pronounce with way less room for mistakes whereas reading is easier.
Russian has a lot of words I can recognise in it. Not just loanwords either but words such as brat, dva, kot (brother, two (twa), cat). The other problem is the tonal system although Mandarin balances that out with simple grammar. Mandarin strikes me as mostly vowels and Russian as strings of consonants.
